How to get rid of scratches and scrapes on side of boat??

I bought a 1992 Prostart this spring. It's been a great boat, but I'd like to take care of some of the scratches on it. What's the best way to get rid of these or make them less visible??

Scratches

I haven't had to deal with anything too deep but for the small stuff and the scuffs, this 3M marine stuff is really good!

Just out of curiosity, What color is your 205?

Depends on how deep the scratches are. If they're not very deep wet sand with 400 then 600 then 800, then 1000, then 1500,then compound and polish. Be careful, gel coat is only so thick and you don't want to sand through to the glass. You can fill deep scratches with gel coat available at West Marine or Boater's World. Gel coat will not cure exposed to air so cover with cellophane tape or polyvinyl alchohol (also at WM or BW). Sand as above after cure of gelcoat.

If gelcoat doesn't cure when it's exposed to air, how does it cure when it's sprayed on by so many boat manufacturers?

Jim, they use the PVC mold release first, then the gel, it will cure, but not completely. They are then laying/spraying the glass over it, which allows it to cure completely and form a chemical bond between the glass and gel.

I'm not talking about MC. On most other boats, the fiberglass is layed up in the mold and the gel is sprayed over that, then they sand and polish it to get the best finish they can. Spraying the mold before laying up the glass is the exception to the rule. Gelcoat also cures from the outside in, from what I was told be someone who has a fiberglass/gelcoat repair shop.

I have had good results with Meguiars no 49 Heavy Duty Oxidation and scratch remover, about $11 a bottle. I used a random orbit action polisher. DO NOT CHEAP OUT A BUY A CHEAP BUFFING PAD! Buy the wool pad for about $12. It won't wear out on the edges. If it wears out on the edges and the buffer jumps, you could make a worse scratch than you already have.
One time for a deep scratch on my 88' I used the Meguiars right on a 2400 and then a 3600 Micro Mesh sandpaper and rubbed by hand until the scratch was gone. After that I did a final buff with the polisher. It worked great.
There will some areas that you can only do by hand but this product also works good just using it without a buffer.
